The upgrade of the CMS detector for the high luminosity LHC (HL-LHC) will include gas electron multiplier (GEM) detectors in the end-cap muon spectrometer. Due to the limited supply of large area GEM detectors, the Korean CMS (KCMS) collaboration had formed a consortium with Mecaro Co., Ltd. to serve as a supplier of GEM foils with area of approximately 0.6 m$^{2}$. The consortium has developed a double-mask etching technique for production of these large-sized GEM foils. This article describes the production, quality control, and quality assessment (QA/QC) procedures and the mass production status for the GEM foils. [...]

The series of upgrades to the Large Hadron Collider, culminating in the High Luminosity Large Hadron Collider, will enable a significant expansion of the physics program of the CMS experiment. However, the accelerator upgrades will also make the experimental conditions more challenging, with implications for detector operations, triggering, and data analysis. [...]

A new technique to establish the uniformity of the induction gap in GEM based detectors / Gola, Mohit (Delhi U.) ; Brunbauer, F. (CERN) ; Janssens, D. (CERN) ; Kumar, A. (Delhi U.) ; Lisowska, M. (CERN) ; Muller, H. (CERN ; Bonn U.) ; Naimuddin, Md. (Delhi U.) ; Oliveri, E. (CERN) ; Pfeiffer, D. (CERN ; ESS, Lund) ; Ropelewski, L. (CERN) et al.
This work is proposing and exploring the use of multichannel readout electronics, already used in quality assurance for gain uniformity studies, to measure the uniformity of the induction gap in GEM based detectors. The measurement will furthermore provide a qualification of the readout electrodes in terms of disconnected or shorted channels. [...]
